Well, one must also take into consideration what is going on at the mansion in the first place. Is Cyke in any condition to be a leader at this point? He could be a bit unstable, and Storm and Logan are the only other adults left to be in charge of anything, right? So the two may have some "quality" time together; arguing, disagreeing, getting on each other's nerves, butting heads...all the while getting to know a bit more about each other.

But as has been said here...sex for sex's sake...big no!!!

I think people also need to take into account that out of the original team, they are the only two left(if the script review is accurate and the deaths still remain). That's three people they were freinds with that they believe are dead. Grief works in strange ways and I can totally see them comforting each other over the fact.
